MPPSC Prelims 2010 Question Paper with Answers & Explanations

Explanation

Alha and Udal were renowned 12th-century legendary warriors who served the Chandela king Paramardideva (Parmal) of Mahoba. They are central figures in the Alha-Khand epic, which recounts their heroic deeds and battles. Their most famous exploits include defending Mahoba against the forces of Prithviraj Chauhan. Mahoba is often referred to as "Alha-Udal Nagari" due to their profound historical and cultural connection to the region.

Explanation

Sir Thomas Roe was the English Ambassador who followed Emperor Jahangir to Mandu from Ajmer. He arrived in India in 1615 as an envoy of King James I to the Mughal court, seeking trade agreements for the East India Company. Roe resided at Jahangir's court for approximately four years, from 1615 to 1619, and his movements often mirrored those of the emperor. During this period, he traveled with Jahangir to various locations, including Ajmer and Mandu.

Explanation

Mohandas Karamchand Gandhi arrived in South Africa in 1893 as a lawyer and remained there for 21 years, occasionally visiting India and England. During his time in South Africa, he developed his philosophy of Satyagraha, a form of nonviolent resistance, and campaigned for civil rights. He returned to India in 1915, at the age of 45, to lead the Indian independence movement. Therefore, Gandhi lived in South Africa for 21 years.

Explanation

Chakravarti Rajagopalachari, often known as Rajaji, was the first and only Indian Governor-General of India. He assumed office in June 1948, succeeding Lord Mountbatten, who was the first Governor-General of the Dominion of India. Rajagopalachari served in this role until January 26, 1950, when India became a republic and the office of Governor-General was abolished, replaced by the President of India. His appointment marked a significant transition as it was the first time an Indian citizen held the highest constitutional post in independent India.

Explanation

Lord Mountbatten served as the last Viceroy of India, overseeing the transfer of power from British rule to the newly independent nations of India and Pakistan. He was appointed in February 1947 with a mandate to expedite the process of independence. His tenure culminated in the partition of India and the granting of independence on August 15, 1947. After independence, he continued as the first Governor-General of the Dominion of India.

Explanation

Mohan Singh, the founder and first commander of the Indian National Army (INA), was not among the officers tried at the Red Fort. He had disagreements with the Japanese leadership and was removed from his command and taken into custody by the Japanese military police in December 1942, before the INA was revived under Subhas Chandra Bose. Although he was later taken into custody by the British and repatriated to India to face trials, public pressure, roused by the INA Red Fort trials, led to him only being cashiered from the Army. The prominent Red Fort trials primarily focused on officers like Shah Nawaz Khan, Prem Sehgal, and Gurbaksh Singh Dhillon, who represented the INA during its later phases.

Explanation

G.V. Mavlankar holds the unique distinction of having served as the Speaker of both the Central Legislative Assembly during the British era and the Parliament of free India. He was elected as the President (Speaker) of the Central Legislative Assembly in January 1946 and continued in that role until India's independence in August 1947. Following independence, he became the Speaker of the Constituent Assembly (Legislative) and then the Speaker of the Provisional Parliament. Subsequently, he was elected as the first Speaker of the Lok Sabha, the lower house of the Parliament of independent India, in 1952, a position he held until his demise in 1956.

Explanation

M.S. Subbulakshmi sang 'Sare Jahan Se Achha Hindustan Hamara' by Iqbal and 'Jana Gana Mana' by Rabindranath Tagore in the Central Assembly at midnight on August 14/15, 1947. This historic performance marked the dawn of India's independence. Her rendition of these patriotic songs resonated deeply during this momentous occasion.

Explanation

Kalidas's work Meghdootam, also known as "Cloud Messenger," contains references to the beauty of Amarkantak. In this lyrical poem, a Yaksha (a nature spirit) sends a message to his beloved through a cloud, describing the picturesque landscapes the cloud will encounter on its journey. Amarkantak, located in the Anuppur district of Madhya Pradesh, is mentioned as part of this topographical description, highlighting its natural splendor and the origin of the Narmada River. The poem vividly portrays various geographical features, including mountains, rivers, and cities, along the cloud's path from Ramagiri to Alaka.

Explanation

The Supreme Court of India is considered the custodian of the Indian Constitution. It acts as the ultimate interpreter and guardian of the Constitution, ensuring that all government branches operate within their constitutional limits. The Supreme Court safeguards the fundamental rights and liberties of citizens and has the power of judicial review to strike down any law or executive action that violates the Constitution. This role is crucial for upholding the rule of law and maintaining the balance of power in India's democratic framework.

Explanation

The Indian Constitution was formally adopted by the Constituent Assembly on November 26, 1949. However, it came into full effect on January 26, 1950, marking the establishment of the Republic of India. On this date, the Constituent Assembly transitioned into the Provisional Parliament of India, operating under the newly adopted Constitution. Therefore, while the drafting body adopted it in 1949, the Constitution began governing the parliamentary system in 1950.

Explanation

The Council of Ministers is collectively responsible to the Lok Sabha, which is a part of the Parliament. This principle of collective responsibility means that the entire Council of Ministers stands or falls together with the government's policies and actions. If a no-confidence motion is passed against the Council of Ministers in the Lok Sabha, the entire ministry must resign. While the President appoints the ministers and the Speaker presides over the Lok Sabha, the ultimate accountability for the government's functioning lies with the elected representatives in the Lok Sabha, and thus the Parliament.

Explanation

The Lok Sabha historically had a total of 545 members. This number comprised 543 members directly elected from territorial constituencies across India. Additionally, two members from the Anglo-Indian community were nominated by the President if their community was not adequately represented. While the provision for nominating Anglo-Indian members was abolished in January 2020 by the 104th Constitutional Amendment Act, 545 was the fixed member number for a significant period.

Explanation

The fixed strength of the Rajya Sabha, as per Article 80 of the Indian Constitution, is 250 members. Out of this, 238 members are representatives of the states and union territories, while 12 members are nominated by the President of India. These nominated members are individuals with special knowledge or practical experience in fields such as literature, science, art, and social service. Although the maximum strength is 250, the current strength of the Rajya Sabha is 245 members.

Explanation

The Rajya Sabha, also known as the Council of States, is a permanent body and is not subject to dissolution. Unlike the Lok Sabha, which can be dissolved, the Rajya Sabha ensures continuity in governance. Its members serve staggered six-year terms, with approximately one-third of them retiring every two years, and new members being elected to fill the vacancies. Therefore, none of the given options correctly describe how the Rajya Sabha is dissolved, making D the correct answer.The Rajya Sabha, also known as the Council of States, is a permanent body and is not subject to dissolution.

Therefore, none of the given options correctly describe how the Rajya Sabha is dissolved, making D the correct answer.

Explanation

The Indian Constitution originally contained 8 Schedules when it was adopted in 1949. Over time, through various amendments, four more Schedules were added. This has resulted in the current total of 12 Schedules in the Indian Constitution. These Schedules provide additional details and classifications not explicitly mentioned in the main Articles, covering diverse topics such as the distribution of powers, official languages, and provisions for local governance.

Explanation

Delhi is a Union Territory, not a full-fledged state. Consequently, the Delhi Police operates under the direct control of the Union Ministry of Home Affairs, which is part of the central government. In contrast, states such as Madhya Pradesh, Bihar, and Uttar Pradesh have their police forces controlled by their respective state governments. This distinction arises from Delhi's unique administrative status as a Union Territory with a legislative assembly.

Explanation

The Indian Constitution guarantees several fundamental rights, including the Right to Equality (Articles 14-18), Right to Freedom (Articles 19-22), and Right to Freedom of Religion (Articles 25-28). While the right to dignified living, which can encompass equitable access to housing, has been interpreted under Article 21 (Right to Life and Personal Liberty), there is no explicitly stated "Right of equal home" as a distinct fundamental right. The Constitution prohibits discrimination in various matters, including those related to housing, but it does not guarantee an explicit right to an "equal home." Therefore, "Right of equal home" is not a directly guaranteed fundamental right in the Indian Constitution.

Explanation

In India, most legislative proposals, known as Bills, can be introduced in either the Lok Sabha (House of the People) or the Rajya Sabha (Council of States). This applies to Ordinary Bills, which deal with matters other than financial subjects. A Bill can be introduced by a Minister (Government Bill) or any other member of Parliament (Private Member's Bill). However, Money Bills, which exclusively deal with financial matters, are an exception and can only be introduced in the Lok Sabha.

Explanation

The Supreme Court of India holds the power to transfer any case anywhere in India. This authority is primarily derived from Article 139A of the Constitution of India, which allows the Supreme Court to withdraw cases from High Courts and transfer them to itself or another High Court if they involve substantial questions of law of general importance. Additionally, Section 25 of the Code of Civil Procedure (CPC) empowers the Supreme Court to transfer any civil suit, appeal, or other proceeding from one High Court or civil court in one state to another High Court or civil court in any other state. For criminal cases, Section 406 of the Code of Criminal Procedure (CrPC) grants the Supreme Court the power to transfer cases and appeals from one High Court to another, or from a criminal court subordinate to one High Court to another criminal court of equal or superior jurisdiction subordinate to another High Court. The Supreme Court exercises this power to ensure a fair trial, prevent injustice, avoid harassment of parties, or consolidate cases pending in different courts.

Explanation

G.V. Mavlankar, often referred to as the "Father of the Lok Sabha," was indeed the first Speaker to discard the official wig. He chose to preside over the house wearing a Gandhica, a traditional Indian attire, symbolizing a break from colonial traditions and embracing Indian identity. This decision reflected the newly independent nation's desire to establish its own parliamentary customs. Mavlankar served as the Speaker of the Central Legislative Assembly and later as the first Speaker of the Lok Sabha of independent India.

Explanation

Dr. Rajendra Prasad was elected as the permanent President of the Constituent Assembly on December 11, 1946. He presided over the Constituent Assembly's deliberations, which were responsible for drafting the Constitution of India. His leadership was crucial in guiding the assembly through the complex process of constitution-making. Dr. B.R. Ambedkar, while a key figure, served as the chairman of the Drafting Committee, not the President of the Constituent Assembly. C. Rajgopalachari and K.M. Munshi were also important members but did not hold the position of President of the Constituent Assembly.

Explanation

At the stroke of midnight on August 14/15, 1947, the Constituent Assembly of India assumed sovereign power. The Indian Independence Act of 1947 formally transferred legislative authority from the British Parliament to the Constituent Assembly. This body, which had been tasked with drafting India's constitution, became the provisional parliament for the newly independent Dominion of India. The Central Legislative Assembly ceased to exist, and while the Interim Government had functioned prior to independence, its specific role in the transfer of sovereign power was superseded by the Constituent Assembly. The Chamber of Princes, representing the princely states, did not assume sovereign power over the dominion of India.

Explanation

The Secretariat of the Parliament of India is independent of the Government. This independence is enshrined in Article 98 of the Constitution, which provides for separate secretarial staff for each House of Parliament. This structure ensures that Parliament receives independent advice and that its directions are executed without interference from the Executive. The Lok Sabha Secretariat, for instance, functions under the Speaker's guidance, and its Secretary-General is answerable only to the Speaker, not the government. This autonomy is crucial for the effective functioning of the legislature.

Explanation

Maulana Azad advocated for the deferment of adult franchise for fifteen years in the Constituent Assembly. He believed that postponing its implementation would allow for a period of education and increased awareness among the Indian populace. This cautious approach aimed to ensure a more informed and responsible electorate, capable of making sound decisions for the newly independent nation. While other prominent leaders like Dr. Rajendra Prasad and Jawaharlal Nehru strongly supported immediate adoption, Azad's argument reflected concerns about widespread illiteracy and the overall readiness of the population to effectively exercise their voting rights at that time.

Explanation

The Finance Bill of the Indian Government is presented in the Lower House, also known as the Lok Sabha. This is because the Finance Bill is considered a Money Bill under Article 110 of the Constitution, which exclusively deals with matters related to taxation, government borrowing, and expenditure from the Consolidated Fund of India. Money Bills can only be introduced in the Lok Sabha, and the Rajya Sabha (Upper House) has limited powers, only being able to recommend amendments within 14 days, which the Lok Sabha may choose to accept or reject. This grants the Lok Sabha ultimate authority over financial matters.

Explanation

The highest temperatures on Earth are typically recorded in the subtropical desert regions, which are predominantly found around 20-30° North latitude. This is due to a combination of factors, including intense direct solar radiation, clear skies, and the presence of large landmasses that heat up rapidly. The subtropical high-pressure belts in these regions lead to descending air, which inhibits cloud formation and precipitation, allowing more solar energy to reach and heat the surface. While the equator receives direct sunlight, its high humidity and cloud cover moderate temperatures. Therefore, 25° North Latitude accurately represents the zone where these conditions converge to produce the highest recorded temperatures.

Explanation

The Summer Solstice in the Northern Hemisphere typically falls on June 21st. This astronomical event marks the moment when the Earth's North Pole is at its maximum tilt towards the Sun, approximately 23.5 degrees. As a result, the Northern Hemisphere experiences the longest period of daylight and the shortest night of the year. The word "solstice" comes from Latin words meaning "sun standing still," referring to the sun's apparent halt in its northward or southward movement before reversing direction. While often considered a full day, the solstice is precisely the instant the hemisphere is most tilted towards the sun.

Explanation

Saturn is hotter than Neptune. The average temperature of Saturn is approximately -140°C (-220°F), while Neptune's average temperature is around -200°C (-330°F). Although both planets are far from the Sun, Saturn is closer than Neptune, receiving more solar radiation. Additionally, Saturn, like other gas giants, generates its own internal heat from gravitational compression and other internal processes, which contributes to its overall temperature. Auroras at Saturn's poles also play a role in heating its upper atmosphere to temperatures higher than expected from solar radiation alone.

Explanation

The Earth orbits the Sun at an average distance of approximately 149.6 million kilometers. This distance is also defined as one Astronomical Unit (AU). While Earth's orbit is elliptical, causing the distance to vary throughout the year, 149.6 million km represents the mean distance. Therefore, option D is the most accurate representation of the Earth's average distance from the Sun.

Explanation

The Earth has five oceans. While historically some models recognized four oceans, the five-ocean model is now widely accepted by most governments and experts. These five distinct oceans are the Pacific, Atlantic, Indian, Arctic, and Southern (also known as the Antarctic) Oceans. The Southern Ocean, encircling Antarctica, was officially recognized by various international bodies in the early 21st century, solidifying the five-ocean classification. This division helps in understanding geographical, climatic, and biological differences across the continuous global ocean.

Explanation

Florida is a state located in the southeastern United States, known for its beaches and theme parks. Mercury, Venus, and Saturn are all recognized planets within our solar system. Mercury is the closest planet to the Sun, Venus is known for its extreme heat, and Saturn is famous for its prominent ring system. Therefore, Florida is not a planet of the solar system.

Explanation

India is the seventh largest country in the world by total area. Its total area is approximately 3.28 million square kilometers. It is preceded by Russia, Canada, the United States, China, Brazil, and Australia in terms of size. India accounts for about 2.4% of the total geographical area of the world.

Explanation

Madhya Pradesh is the largest tribal state in India in terms of its absolute Scheduled Tribe (ST) population. According to the 2011 Census, the state is home to 15,316,784 tribal individuals, which is the highest among all Indian states. This significant number makes Madhya Pradesh the tribal heartland of the country. While some states have a higher percentage of tribal population relative to their total population, Madhya Pradesh has the largest tribal population by sheer numbers.

Explanation

Narmada and Tapi are two major rivers in Madhya Pradesh that exhibit a unique westward flow, ultimately draining into the Arabian Sea. This westward direction is attributed to their passage through rift valleys formed by geological faulting. In contrast, most other significant rivers originating in Madhya Pradesh, such as the Chambal, Sindh, Betwa, Ken, and Son, are part of the larger Ganga river system. These rivers generally flow northward or eastward to join the Yamuna or the Ganges, which then empties into the Bay of Bengal. Similarly, rivers like the Wainganga and Pench flow southwards to merge with the Godavari river, another major system that discharges into the Bay of Bengal.

Explanation

Madhya Pradesh consistently holds the distinction of having the largest forest cover by area among all Indian states. According to the India State of Forest Report (ISFR) 2023, Madhya Pradesh has over 77,000 sq km of forest area. This extensive forest land is crucial for biodiversity and wildlife conservation, housing diverse forest types including tropical moist and dry deciduous forests. The state's significant forest cover contributes substantially to India's overall green cover and is home to numerous national parks and wildlife sanctuaries.

Explanation

As of 2010, the Food and Agriculture Organization of the United Nations estimated India's forest cover to be approximately 22% of the country's total area. While more recent reports, such as the India State of Forest Report (ISFR) 2023, indicate the forest cover is around 21.76% of the geographical area, the option of 22.7 percent is the closest available choice. This figure reflects the significant portion of Indian land dedicated to forest areas.

Explanation

Mount Everest, the world's highest mountain, is situated on the border between Nepal and the Tibet Autonomous Region of China. The summit of Mount Everest itself lies directly on this international border, meaning it is shared by both nations. However, the most popular climbing route, the South Col Route, and the iconic Everest Base Camp are located on the Nepalese side. Therefore, among the given options, Nepal is the correct answer.

Explanation

The Tehri Dam is constructed on the Bhagirathi River, which is a major headstream of the Ganga (Ganges) River. The Bhagirathi originates from the Gaumukh region near the Gangotri glacier and flows until it meets the Alaknanda River at Devprayag. From this confluence point onwards, the river is known as the Ganga. Therefore, while the dam is directly on the Bhagirathi, it is considered to be on a river that forms the Ganga.

Explanation

K2, also known as Mount Godwin-Austen, is considered India's highest mountain peak because it lies in the Karakoram mountain range, within the region of Gilgit-Baltistan, which India claims as its integral territory. Standing at 8,611 meters (28,251 feet), it is the second-highest mountain in the world. Mount Everest, while the world's highest, is located on the border of Nepal and China, not India. Siachen is a glacier, not a mountain peak, and Kargil is a town and district in Ladakh, not a peak. Therefore, based on India's territorial claims, K2 is the highest peak.

Explanation

The Western Ghats, Himalayan Region, and Meghalaya experience the highest rainfall in India due to their geographical features and interaction with monsoon winds. The Western Ghats, a mountain range along India's west coast, intercept moisture-laden monsoon winds from the Arabian Sea, causing significant orographic precipitation on their windward side. Meghalaya, particularly places like Mawsynram and Cherrapunji, is renowned for receiving exceptionally high rainfall, often considered among the wettest places on Earth, due to the funneling effect of its hills on monsoon clouds from the Bay of Bengal. The eastern parts of the Himalayan region also receive substantial rainfall from the Bay of Bengal monsoon branch, with precipitation increasing with altitude up to a certain point. These regions' topography forces moist air to rise, cool, and condense, leading to heavy rainfall.

Explanation

Rice is a water-intensive crop that requires a hot and humid climate for optimal growth. It needs significant rainfall, with an annual average typically exceeding 100 cm. While some sources indicate an average annual rainfall requirement of 150 cm or more for ideal conditions, 100 cm is generally considered the minimum threshold for rainfed rice cultivation in India. In areas receiving less than 100 cm of rainfall, rice can still be grown successfully, but it necessitates extensive irrigation.

Explanation

The Sahara Desert is the world's largest hot desert, covering an immense area of approximately 9.2 million square kilometers (3.6 million square miles) across much of North Africa. This vast desert spans eleven countries, making it a dominant geographical feature of the continent. In comparison, the Gobi Desert is about 1.3 million square kilometers, the Great Sandy Desert is around 284,993 square kilometers, and the Gibson Desert is approximately 155,000 square kilometers, all significantly smaller than the Sahara. Thus, among the given choices, the Sahara is the largest.

Explanation

The Nile River is widely recognized as the world's longest river, flowing approximately 6,650 kilometers (4,132 miles) from its source to the Mediterranean Sea. It traverses through eleven countries in northeastern Africa, playing a crucial role in the history and development of ancient civilizations like Egypt. While there has been some debate and varying measurements regarding its exact length compared to the Amazon River, the Nile traditionally holds the title. Its immense length and historical significance make it a prominent geographical feature.

Explanation

The world's deepest oceanic deep is the Mariana Trench. Specifically, its deepest point is known as the Challenger Deep, located in the western Pacific Ocean. This crescent-shaped trench stretches for about 2,550 km and reaches an approximate maximum depth of 10,984 meters (36,037 feet). The immense depth of the Mariana Trench is a result of the subduction of the Pacific Plate beneath the smaller Mariana Plate, a process where one tectonic plate slides beneath another.

Explanation

Lake Baikal is the largest freshwater lake in the world by volume. It contains approximately 22-23% of the world's fresh surface water, exceeding the combined volume of all the North American Great Lakes. This ancient lake, located in Siberia, Russia, is also the deepest lake globally, with a maximum depth of 1,642 meters (5,387 feet). Its immense depth and vast volume contribute to its status as the world's largest freshwater reservoir.

Explanation

China is by far the largest coal producer among the given countries, consistently ranking as the world's top producer for decades. In 2024, China alone accounted for more than half of the world's coal production, with nearly 4.8 billion tonnes. This output significantly surpasses that of Australia, which produced around 463 million tonnes in 2024, and is vastly greater than the production of Brazil and New Zealand, both of which have comparatively very low coal outputs. China's immense coal production is driven by its substantial energy demands, with coal supplying over 60% of the nation's power.

Explanation

The Amazon basin is the native home of the Hevea brasiliensis rubber tree, which is the primary source of natural rubber. This region provides the ideal tropical climate with high rainfall and humidity necessary for the extensive growth of these trees. Similarly, the Zaire (Congo) basin in Africa offers comparable environmental conditions, making it another significant area for natural rubber production and cultivation. Both basins possess vast tracts of tropical rainforests, historically supporting the widespread presence of rubber-producing trees.

Explanation

Galileo Galilei is widely credited with inventing the thermoscope, an early form of thermometer, around 1593 or 1597. His device demonstrated changes in temperature through the expansion and contraction of air, which caused a column of water to move. While it could indicate temperature differences, it lacked a standardized scale, which was later added by others to create the true thermometer.

Explanation

Sir Isaac Newton is credited with developing the theory of universal gravitation. He published his seminal work, "Philosophiæ Naturalis Principia Mathematica," in 1687, which described gravity as a universal force of attraction between masses. Newton's law states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This theory unified celestial and terrestrial mechanics, explaining phenomena such as tides and planetary orbits. While Albert Einstein later developed the theory of general relativity, which refined Newton's work, Newton's law of universal gravitation remains a foundational concept in physics.

Explanation

Vinegar is an aqueous solution primarily composed of acetic acid. Acetic acid, also known as ethanoic acid, is the active component that gives vinegar its characteristic sour taste and pungent odor. It is produced through a two-stage fermentation process where yeast converts sugars to ethanol, and then acetic acid bacteria oxidize the ethanol into acetic acid. Commercial vinegars typically contain between 4% and 8% acetic acid.

Explanation

The pH value of human blood is tightly regulated within a narrow, slightly alkaline range. The normal pH of human blood is between 7.35 and 7.45. This specific range is crucial for various biological processes, including enzyme function and oxygen transport. Deviations outside this range, either becoming too acidic (acidosis) or too alkaline (alkalosis), can lead to serious health problems. Therefore, option A, 7.36 to 7.42, accurately represents the normal pH range of human blood.

Explanation

A fever is defined as a temporary rise in body temperature above the normal range. It is not an illness itself, but rather a symptom indicating that an abnormal process, often an infection, is occurring in the body. The body's "thermostat," located in the hypothalamus, resets to a higher temperature during a fever. While normal body temperature varies, a temperature of 100.4°F (38°C) or higher is generally considered a fever.

Explanation

Mitochondria are often called the "powerhouses" of the cell because they are responsible for generating the majority of the cell's energy. This energy is produced in the form of adenosine triphosphate (ATP) through a process called cellular respiration. During cellular respiration, mitochondria break down glucose and other nutrients in the presence of oxygen to create ATP, which fuels various cellular activities like muscle contraction, nerve impulse propagation, and chemical synthesis. Cells that require a lot of energy, such as muscle cells, contain thousands of mitochondria.

Explanation

Animal cells lack a cell wall, which is a rigid outer layer found in plant cells. This cell wall in plants is primarily composed of cellulose, a complex carbohydrate that provides structural support and protection. Instead of a cell wall, animal cells have a flexible plasma membrane as their outermost boundary. While a few exceptions exist, such as tunicates, the presence of a cellulose cell wall is a defining characteristic that distinguishes plant cells from animal cells.

Explanation

Bats are the only mammals capable of true, sustained flight. Their wings are modified forelimbs with a membrane of skin stretched between elongated fingers and their body. Jaguars are mammals but cannot fly; they are known for their climbing and swimming abilities. Ostriches are birds, not mammals, and while they have wings, they are flightless. Pelicans are also birds, not mammals, and are known for their ability to fly and catch fish.

Explanation

The blue whale (Balaenoptera musculus) is the largest mammal on Earth, and also the largest animal known to have ever existed. These magnificent marine creatures can reach lengths of up to 110 feet (33.58 meters) and weigh as much as 190 to 200 tons (approximately 400,000 pounds). To put this into perspective, a blue whale's weight is equivalent to about 33 elephants. In contrast, African elephants, the largest land mammals, typically weigh between 5,000 to 14,000 pounds (2,268 to 6,350 kilograms). Hippopotamuses average around 3,000 to 9,900 pounds, and polar bears typically weigh between 600 to 1,700 pounds.

Explanation

Blood's primary function is to transport oxygen from the lungs to all the cells and tissues throughout the body. It also carries nutrients, hormones, and waste products. While blood is a liquid and helps maintain the body's fluid balance, "maintains liquidity" isn't a direct function of what blood does in the body. Blood does not directly help in digestion; that is the role of the digestive system. Blood flow is involved in erection, but it's not a general function of blood itself, rather a physiological process involving blood.

Explanation

The average speed of a bee can vary depending on factors such as whether it is carrying a load. Honey bees typically fly at an average speed of about 15 miles per hour (approximately 24 km/h) when unladen. When carrying nectar or pollen, their speed tends to decrease to around 12 miles per hour (approximately 19 km/h). Research indicates that the flight speed of bees with a load ranges from 21 to 26 km/h, with an average of about 24 km/h. Therefore, 24 km/h is a factually accurate representation of a bee's average speed.

Explanation

The average weight for a 14-year-old teenage boy typically falls within a broad range, reflecting individual growth and development. According to growth charts, a healthy weight for a 14-year-old boy can range from approximately 46.3 kg to 88.5 kg (102 to 195 pounds). Another source indicates a range of 84 to 160 pounds (approximately 38 to 72.5 kg) for 14-year-old males. Therefore, 47 kg is well within the healthy and average weight range for a boy of this age. The other options provided (12kg, 14kg, 25kg) are significantly below the healthy weight range for a 14-year-old boy.

Explanation

The human heart has four chambers: two upper chambers called atria (right and left atrium) and two lower chambers called ventricles (right and left ventricle). These chambers work together as a two-sided pump to efficiently circulate blood throughout the body. The right side of the heart receives deoxygenated blood and pumps it to the lungs, while the left side receives oxygenated blood from the lungs and pumps it to the rest of the body. This separation ensures that oxygen-rich and oxygen-poor blood do not mix, allowing for efficient oxygen delivery.

Explanation

Copper is an essential trace element necessary for human health and metabolism. In contrast, cadmium, arsenic, and nickel are all recognized as toxic heavy metals and significant environmental pollutants. Cadmium is a non-essential metal that accumulates in the body and is linked to various cancers and organ damage. Arsenic, particularly in its inorganic form, is highly toxic, a confirmed human carcinogen, and a widespread contaminant in drinking water. Nickel is also a known contaminant that can cause allergies, cardiovascular and kidney diseases, and is considered an immunotoxic and carcinogenic agent. While excessive levels of copper can be harmful and its mining can cause localized pollution, copper itself is not classified as a toxic air contaminant or a human carcinogen, unlike the other options.

Explanation

A lactating mother requires an increased protein intake to support both her own nutritional needs and the production of breast milk for her baby. The National Institutes of Health (NIH) currently recommends that breastfeeding mothers consume around 71 grams of protein daily. This amount is considered adequate for milk production, tissue repair, and maintaining energy levels during the postpartum period. While some research suggests that optimal protein intake might be higher, 70 grams aligns with established guidelines for preventing deficiencies.

Explanation

Picture messages, often sent via Multimedia Messaging Service (MMS) or through messaging applications, typically have a retention period. For instance, in services like iMessage, deleted messages and their attachments remain in a "Recently Deleted" folder for 30 days before permanent removal. Similarly, some messaging platforms may retain message bodies in backups for up to 30 days after a user deletion request. This 30-day period is a common timeframe for the temporary storage of deleted media messages in private inboxes before they are permanently purged from the system.

Explanation

Cache memory has the shortest access time because it is a small, high-speed memory located directly on or very close to the CPU. Its purpose is to store frequently accessed data and instructions, allowing the CPU to retrieve them much faster than from main memory (RAM). Magnetic bubble memory and magnetic core memory are older, slower technologies primarily used for non-volatile storage, not for direct CPU access. While Random Access Memory (RAM) is faster than magnetic storage, cache memory is designed to be even faster and acts as a buffer between the CPU and RAM.

Explanation

Microsoft Word is an example of application software because it is designed to perform specific tasks for end-users, such as creating, editing, and formatting documents. Unlike system software, which manages computer hardware and resources, application software focuses on user-oriented functions. An operating system, for instance, is system software that manages the computer's basic functions and acts as an interface between the user and hardware. Input devices are hardware components used to send information to a computer, like a keyboard or mouse, while processing devices are hardware components, such as the CPU, that execute instructions and manage data flow. Therefore, Microsoft Word, a word processor, clearly falls under the category of application software.

Explanation

Hacking is the act of gaining unauthorized access to computer systems, networks, or data, often by exploiting vulnerabilities in software, hardware, or human behavior. It involves manipulating digital systems to perform actions they weren't intended to allow, which can be for malicious purposes like stealing data or disrupting operations, or for ethical purposes like penetration testing to improve security. Therefore, "searching" is too broad and does not capture the unauthorized access aspect, and while "security" is related to the field of hacking (both in terms of bypassing and improving it), it is not a definition of hacking itself.

Explanation

Virtual memory is a technique that allows a computer to compensate for physical memory (RAM) shortages by temporarily transferring data from RAM to disk storage. The operating system uses a portion of the hard drive, known as a swap file or paging file, to store data that doesn't fit into RAM. Therefore, the maximum size of the virtual memory available to the system is directly dependent on the amount of free disc space allocated for this swap file. Address lines determine the maximum physical memory a CPU can address, not the size of virtual memory, and a database is an application, not a factor in virtual memory size.

Explanation

Orkut was a social networking service launched by Google in 2004, designed for users to connect with friends and meet new people.

It works by sending focused ultrasonic energy or high-energy shock waves, often guided by X-rays or ultrasound, directly to the stone. These shock waves break the large kidney stone into smaller fragments. These smaller pieces can then more easily pass out of the body in the urine over several days or weeks. This procedure allows patients to avoid invasive surgical procedures for stone removal.

Explanation

Shifting cultivation, locally known as jhum, is a traditional agricultural practice in Nagaland that involves clearing forest land by felling and burning trees to prepare it for cultivation. This practice leads to significant deforestation and exposes the soil to erosion, especially on mountain slopes. The traditional long fallow periods, which allowed forests to regenerate, have drastically shortened due to increasing population pressure and the need for more arable land. This reduced regeneration time prevents the natural recovery of the forest cover and soil fertility, ultimately contributing to the barrenness of the mountains.

Explanation

Charles Darwin is widely credited with propounding the theory of evolution through natural selection. His seminal work, "On the Origin of Species," published in 1859, detailed how species evolve over generations through the inheritance of traits that enhance survival and reproduction in a given environment. While Alfred Russel Wallace independently arrived at similar conclusions regarding natural selection, it was Darwin who extensively developed and popularized the theory. Herbert Spencer applied evolutionary concepts to sociology, coining the phrase "survival of the fittest," but his work focused on social evolution rather than biological evolution. Thomas Huxley was a strong advocate for Darwin's theory and played a crucial role in its public acceptance, but he did not originate the theory itself.

Explanation

Goa remained under Portuguese control after August 15, 1947, when India gained independence from British rule. The Portuguese refused to relinquish their territories in India, including Goa, Daman, and Diu, despite repeated requests from the Indian government. These territories were eventually liberated by the Indian armed forces in December 1961 through a military operation known as "Operation Vijay". Goa then became a Union Territory and later achieved statehood in 1987.

Explanation

Bhopal, the capital city of Madhya Pradesh, is famously known to be situated on seven hills. These prominent hills contribute to the city's uneven elevation and distinct landscape. Some of the well-known hills include Arera Hills, Shyamla Hills, and Idgah Hills. This geographical feature is a defining characteristic of Bhopal, often referred to as the "City of Lakes and Hills."

Explanation

Bhopal is home to the Taj-ul-Masajid, which is recognized as India's largest mosque. This grand mosque, whose name translates to "Crown of Mosques," is a significant example of Indo-Islamic architecture. It boasts a distinctive pink sandstone facade, two towering minarets, and a vast courtyard capable of accommodating a large number of worshippers. The construction of the Taj-ul-Masajid was initiated by Nawab Shah Jahan Begum of Bhopal.

Explanation

According to the 2011 Census of India, there were approximately 640,932 villages in the country. This figure is often rounded to about 6.4 lakh villages. Therefore, the option of 6 lakh 30 thousand (6,30,000) is the closest approximation to the actual number of villages recorded in India during that census. While more recent estimates suggest a slight increase, the 2011 Census remains a primary reference for such data.

Explanation

Zubin Mehta is a renowned Indian conductor of Western classical music, known for leading orchestras worldwide. Nirad C. Chaudhari was a prominent Indian writer, cultural commentator, and historian. Vikram Seth is a celebrated Indian novelist and poet. Arundhati Roy is an acclaimed Indian author and political activist. Therefore, Zubin Mehta is the only individual among the options who is not primarily known as a writer.

Explanation

Aamir Khan's film "Lagaan" (2001) was nominated for an Academy Award in the Best Foreign Language Film category. This makes it the only movie directly associated with Aamir Khan as an actor and producer to receive an Oscar nomination. While "Mother India" (1957) and "Salaam Bombay!" (1988) were also nominated for Best Foreign Language Film, bringing the total Indian nominations in that category to three, Aamir Khan was not involved in the production or acting of those two films. Therefore, only one of Aamir Khan's movies has been nominated for an Oscar.

Explanation

Goa is a full-fledged state in India, having achieved statehood on May 30, 1987. Lakshadweep, Dadra and Nagar Haveli and Daman and Diu (which were merged in 2020), and Chandigarh are all Union Territories of India. Union Territories are directly governed by the central government, unlike states which have their own elected state governments. Therefore, Goa is not a Union Territory.

Explanation

Adam Smith is widely recognized as the father of modern economics. His seminal work, "An Inquiry into the Nature and Causes of the Wealth of Nations," published in 1776, laid the foundational principles of classical free-market economic theory. In this book, Smith introduced key concepts such as the division of labor, the invisible hand, and the idea that rational self-interest and competition can lead to economic prosperity. His work marked the inception of modern economic scholarship as a comprehensive system and an academic discipline, moving away from earlier explanations of wealth distribution based on divine will. Smith's ideas significantly shaped economic thought and continue to influence economic policy and theory today.

Explanation

The pattern from BREAD → DBARE is determined by the position sequence: B(1) R(2) E(3) A(4) D(5) → D(5) B(1) A(4) R(2) E(3), giving the rearrangement order 5-1-4-2-3.

Applying 5-1-4-2-3 to each option: A) SWORN: N(5) S(1) R(4) W(2) O(3) → NSRWO. Given: NSOWR. ✗ B) GLAZE: E(5) G(1) Z(4) L(2) A(3) → EGZLA. Given: EGZAL. ✗ C) LOWER: R(5) L(1) E(4) O(2) W(3) → RLEOW. Given: RLEWO. ✗

None of the options produce the correct rearranged word, so the answer is D) None of these.

Explanation

"Ram is sitting to the immediate left of Hari" implies that if Hari is at a position, Ram is at the position immediately counter-clockwise to Hari. "Shiv is sitting to the right of Kamal" means that Kamal is immediately followed by Shiv in a clockwise direction. Given that Ram is not next to Kamal, the only possible clockwise arrangement of the four friends that satisfies all conditions is Hari, Kamal, Shiv, Ram. Therefore, in this arrangement, Kamal is sitting to the immediate right of Hari.

Explanation

At 3:30, the minute hand points directly at the 6. The hour hand is exactly halfway between the 3 and the 4. Each hour mark on a clock represents 30 degrees (360 degrees / 12 hours). At 3:30, the minute hand is at 180 degrees from the 12. The hour hand is at 3 hours * 30 degrees/hour + 30 minutes * 0.5 degrees/minute = 90 degrees + 15 degrees = 105 degrees from the 12. The difference between these two positions is 180 degrees - 105 degrees, which equals 75 degrees.

Explanation

To calculate 72% of 418, convert the percentage to a decimal by dividing 72 by 100, which results in 0.72. Then, multiply this decimal by 418. The calculation is 0.72 * 418 = 300.96. Therefore, 72% of 418 is 300.96. The provided option B) 23.9096 does not correspond to this accurate mathematical calculation.

Explanation

The Vice President of India serves as the ex-officio Chairman of the Rajya Sabha. Dr. Hamid Ansari held the esteemed office of Vice President of India for two consecutive terms, from 2007 to 2017. Consequently, throughout his tenure as Vice President, he also served as the Chairman of the Rajya Sabha. Therefore, in the context of the period he served, Dr. Hamid Ansari was indeed the Chairman of the Rajya Sabha.
